Dodoma Urban Water Supply and Sanitation Authority

What Dodoma Urban Water Supply and Sanitation Authority does

Dodoma Urban Water Supply and Sanitation Authority (DUWASA) is a Category A autonomous public utility established under the Water Supply and Sanitation Act No. 5 of 2019, serving Dodoma City and the surrounding towns of Bahi, Chamwino, Kongwa, and Kibaigwa in Tanzania. The utility was declared autonomous on 13 February 1998 and inaugurated on 1 July 1998, operating under the oversight of the Ministry of Water with tariff and standards regulation from EWURA. As a government statutory authority, DUWASA fully covers its operations and maintenance costs and a portion of capital investment requirements.

DUWASA's core product is piped potable water supply drawn from four groundwater well fields — Makutopora (61,500 m³/day installed capacity across 17 boreholes), Nzuguni, Ihumwa, and Iyumbu — supplemented by 28 peri-urban boreholes. Total average production is 79,100 m³/day, distributed through a 393 km network (47.983 km trunk main, 345.017 km distribution) and stored in 10 elevated tanks with 92,000 m³ aggregate capacity. The sanitation business operates a 122.1 km sewerage network serving approximately 8% of the population, four waste stabilization ponds (3,672 m³/day) in Swaswa, and a 900 m³/day automated baffle reactor at Benjamin Mkapa Hospital. Revenue is generated from monthly water tariffs billed via USSD *152*00# and an online portal, fixed-rate sewerage removal (TZS 30,000 domestic, TZS 40,000 commercial), connection fees, bowser services, and reconnection charges, with free water provided to vulnerable elderly customers. Distribution is direct through piped networks, headquarters and zone offices in Kongwa and Kibaigwa, and the online platform, supported by community engagement programs including Wiki ya Huduma kwa Mteja (Customer Service Week) and Wiki ya Utumishi wa Umma (Public Service Week).

Key institutional customers include the University of Dodoma, Benjamin Mkapa Hospital, Government City ministries, and named educational institutions. Current performance metrics show 91% water coverage in Dodoma City with a 100% target by 2030, 82% of population receiving clean water, 36,000 home families with water access, and 5,152 with sewerage connections. Ongoing capital projects include the Magufuli City Sewerage and Wastewater Treatment Project (with BCEG China as implementation partner), a planned 35,000 m³/day sanitation expansion, the Farkwa Dam, and integration of the Lake Victoria bulk water supply system.

Recent moves7 records

Others

• Energy and Water Utilities Regulatory Authority (EWURA): Tanzania's sector regulator for water and energy utilities, which sets DUWASA's tariffs, service standards, and licensing conditions. Not a peer in the commercial sense, but a critical counterpart whose regulatory framework defines DUWASA's commercial environment and expansion pathway.

Direct peers

• Dar es Salaam Water and Sewerage Authority (DAWASA): Tanzania's largest urban water and sewerage authority, operating under the same Water Supply and Sanitation Act framework and EWURA oversight as DUWASA. DUWASA's Managing Director previously served at DAWASA, and the two organisations run joint training programmes, making DAWASA the closest direct operational peer.
• Moshi Urban Water Supply and Sanitation Authority (MOWASCO/MUWASA): Category-tier Tanzanian urban water utility serving the Moshi municipality. DUWASA's MD previously served as Acting Managing Director at Moshi WSSA, and the two share the same regulatory regime, tariff structure, and operational mandate under the Ministry of Water.
• Mbeya Urban Water Supply and Sanitation Authority (MbUWASCO): Tanzanian urban water and sanitation authority serving Mbeya City, operating under identical legal and regulatory frameworks as DUWASA. Comparable as a same-tier utility providing piped water, sewerage, and customer service operations in a regional capital context.
• Arusha Urban Water Supply and Sanitation Authority (AUWSA): Another Category A Tanzanian urban water and sanitation authority serving Arusha City. AUWSA operates under the same legal framework, EWURA tariff regime, and ministerial oversight, providing a directly comparable service model and peer benchmark for DUWASA.
• Mwanza Urban Water Supply and Sanitation Authority (MTUWASCO): Major Tanzanian urban water utility serving Mwanza City, classified similarly under the Water Supply and Sanitation Act. Comparable in scale and regulatory environment, MTUWASCO offers a benchmark on tariff structures, non-revenue water management, and peri-urban service delivery relevant to DUWASA.

Broad incumbents

• National Water and Sewerage Corporation (NWSC) Uganda: Uganda's national parastatal water and sewerage corporation, serving multiple urban centres. While operating under a different national framework, NWSC is a comparable large-scale African public water utility with similar capital-city mandates, infrastructure programmes, and donor-funded capex pipelines relevant to benchmarking DUWASA's institutional model.

Regional players

• Nairobi City Water and Sewerage Company Limited (NCWSC): East African capital-city water utility serving Nairobi, Kenya. Comparable in serving a national capital with high institutional demand, mixed peri-urban coverage, and significant sewerage expansion needs. Provides a regional benchmark for capital-city utility economics relevant to Dodoma's trajectory.
